I got mine in the mail and setup and installed myself, and one extra thing to check is to make sure your ball head isn't tilted down too much. There's a series of measurements you need to follow to find out what angle that things needs to be set as, and when I changed trucks I didn't re-adjust it.
What happened was because I didn't re-adjust, the new truck sat at a slightly different rake, causing my spring bars and subsequently, my cam arms to be too close to the ground.
I then made a slow right turn on a V shaped hill and basically dragged my spring bars on the ground a few inches (I didn't have enough clearance). Fortunately, the cam arms did not hit, and I was able to just sand and repaint the tips of my spring bars (But I didn't realize till later it was blue paint, so now I have a very unique half black / half blue spring bars
Anyways, just to be safe I adjusted ball head, re torqued all the bolts, re measured and retested. She's running great, but it was a bit of a pain.
Point is, if anything changes, I'd re check everything. Also, I do it just about every other outing too, just to be safe.
